(CNN/CNN Newsource) - Archaeologists might have just discovered the first ancient human DNA on the Indonesian island of Sulawesi.

They found bones of a teenage hunter-gatherer who died more than seven thousand years ago. New research published on Wednesday in the journal Nature says this distinct human lineage has never been found anywhere else in the world.

The Leang Panninge remains were likely of a person of the Toalean culture, a group who disappeared about 1,500 years ago.

Nicknamed Bessé’, the young woman's DNA showed that she descended from the first wave of modern humans to enter Wallacea 50,000 years ago -- a distant relative of Aboriginal Australians and Papuans.

An archaeologist says the findings "suggests that there might have been a distinct group of modern humans in this region that we really had no idea about."

Researchers say the latest findings are one piece of the puzzle as they work to understand the ancient genetic history of humans in Southeast Asia.
